The New York City Office of the Chief Medical Examiner announced on Wednesday, April 15, that actress Michelle Trachtenberg died from natural causes related to complications of diabetes mellitus. This announcement came nearly two months after the 39-year-old actress was discovered unresponsive in her Manhattan apartment on February 26, 2025.
Trachtenberg, known for her roles in “Buffy the Vampire Slayer,” “Gossip Girl,” and the 1996 film “Harriet the Spy,” was found after officers responded to a 911 call. Authorities noted no evidence of foul play at the location.
According to People magazine, which initially reported the confirmation from the medical examiner’s office, the manner of death was classified as natural. The specific diabetes-related complications were not detailed by officials.
Sources familiar with the situation disclosed that Trachtenberg had undergone a liver transplant before her death, though the timing and reasons for the procedure remain unspecified. An anonymous source informed NBC News about the transplant, emphasizing possible links between diabetes and liver health.
Medical professionals observe that diabetes can increase the likelihood of nonalcoholic fatty liver disease, which may lead to severe liver scarring or cirrhosis. The connection is bidirectional, as both nonalcoholic fatty liver disease and Type 2 diabetes share several risk factors.
The medical examiner’s office respected the family’s religious objections to performing a traditional autopsy. Trachtenberg’s family, who adhere to Orthodox Jewish customs, generally oppose altering the body after death. Officials determined the cause of death through laboratory tests without a full post-mortem examination.
According to US Magazine, those close to Trachtenberg observed changes in her health in the year leading up to her death. Sources described her as “pale, gaunt, very thin” and noted she had been “really, really sick” and “struggling” with her health issues.
Despite her health challenges, Trachtenberg had previously addressed critics commenting on her appearance via social media. Throughout her career, she remained private about her medical conditions.
Trachtenberg began her acting career as a child, appearing in TV commercials before landing significant roles. Her performance in “Harriet the Spy” highlighted her talent, while her role as Dawn Summers on “Buffy the Vampire Slayer” expanded her audience alongside Sarah Michelle Gellar.
Her portrayal of Georgina Sparks on “Gossip Girl” showcased her acting range and became one of her most notable roles. Trachtenberg also appeared in films like “EuroTrip” and “Ice Princess,” demonstrating her versatility across genres.
Following her death, former co-star Sarah Michelle Gellar expressed her grief on social media, praising Trachtenberg’s talent and character. Gellar described her as fiercely loyal, brave, and true to herself.
Diabetes affects approximately 38 million Americans and is the eighth leading cause of death in the United States, according to ABC News. The condition can lead to various complications, including cardiovascular issues, eye disease, nerve damage, kidney disease, and skin conditions.
For transplant recipients like Trachtenberg, diabetes complications can be particularly difficult. Research indicates that new-onset diabetes can sometimes occur after organ transplantation, potentially due to anti-rejection medications.
At the time of her death, Trachtenberg was active in the entertainment industry and was reportedly planning to attend the SXSW Festival shortly before her passing. Her sudden death surprised fans who were largely unaware of her health struggles.
The revelation of Trachtenberg’s cause of death comes as her peers and fans continue to mourn her loss. Other “Gossip Girl” cast members, including Chace Crawford, and colleagues from her various projects, have paid tribute to the actress, remembering her contributions to film and television.
